COMBINED FURNACE'AND STOVE OR RANGE.

SPECIFICATION forming part of Letters Patent No. 540,365, dated June 4, 1895.

Application filed May 11, 1894. Renewed May 4:, 1895- Serial No. 548,165- (No model.)

, To all whom it may concern:

set forth in the following specification and accompanying drawing.

My invention consists of a furnace having a flue or flues for conducting heat to the place of service, and another flue leading to a cooking stove'or range, and means for diverting the. heat both in the furnace and stove or range, all as will be hereinafter described.

The figure represents a vertical section of a furnace and stove embodying my invention.

Referring to the drawings, A designates a furnace which has the dome or heating drum B, and the air space 0 with which the hot air flue D communicates, the latter passing up through the building and having the outlets E for the various rooms, in which hot air registers may be placed. A flue F leads from the fire chamber of the furnace directly to the smoke flue G.

H designates a flue which leads from the fire chamber of the furnace to a cooking stove or range J. In said flue H is a damper K which has a connection with one end of a bell crank L, the latter being pivoted to a suitable point. Attached to the other arm of the bell crank L are the two cords M and Q, the cord or connection M passing over a roller N, and being fastened to a damper P, in the flue F, the other cord Q passing up through the floor to the room above, where it is attached to an elbow lever B, by means of which said crank L can be operated, said dampers K and P being so arranged that when one is open the other is closed, and vice-versa;

T designates an oven in the chamber D of the stove J, and around said oven isa passage V which communicates with the flue H.

In the chamber D isa partition S, and between it and the oven T is an opening F, in which is situated the three-way valve U having the wings 1, 2 and 3 said valve being operated from the exterior of the stove J, and so arranged, that when in the position as shown in the drawing, that is when the passage V is closed, the heat and particles of com- The fiue W passes through the floor and enters the room above, where it may be utilized for heating the same, and the products of combustion then conducted to the smoke flue G. A flue A leads from said flue W directly into the smoke flue G, and dampers l3 and O in the respective flues A and W permit the closing of the flue WV if it is not desired to conduct the heat to the floor above.

The operation is as follows: The air in the space 0, entering at the point E is heated as usual, and passes up through the flue D, whence it is permitted to escape at desired points. The damper K being closed and the damper P being open, the smoke and products of combustion pass into the smoke flue G through the flue F. If it is desired to heat the interior of the stove, or range J, the elbow lever B is operated. This opens the damper K and closes the damper P, whereupon all the products of combustion pass directly into the stove J. If it is desired to bake, the valve 'U is turned in the direction of the arrow, and the heat passes around the oven T. If the cooking is to be done in the top of the stove, the passage V is closed and the heat is conducted to the chamber D, as shown in the drawing. In either case, the heat, smoke, &c.,-leaves the stove through the flue W, and if the room above is to be heated the damper B in the flue A is closed, and the damper O is opened, whereby the heat will pass up the said flue, and thence into the smoke flue G.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. Arstove having a chamber, a partition therein, an oven in'said chamber, an opening between said partition and said oven, a threeway valve in said opening, a passage around said oven, which is adapted to be closed by said valve, in combination with a furnace having a hot air chamber, a smoke flue leading to a chimney, a second smoke flue leading into the stove, and dampers in said smoke flues which are adapted to operate in unison, all substantially as described.

2. In a combined furnace, and stove, a stove having a chamber D, a partition S therein, an oven T in said chamber, an opening F between the said partition and oven, a threeway valve U in said opening F, a passage V surrounding said oven, and a heat supplying flueleading into said stove adjacent to said valve, said parts being combined substan- I5 tially as described.

3. The furnace A, hot air chamber G, hot air flue D, smoke flue F, flue H, dampers in said fines F and H adapted to be operated in unison, a stove J having the chamber D and oven T, passage V the three-Way valve U, and fines W and A, the latter being provided with the dampers G, and A, said parts being combined substantially as'idescribed.
